Abstract
The aim of this prospective, observational study was to evaluate the effectiveness of a simple endoscopic method for scoring swallowing function after treatment of advanced head and neck cancer patients. A prospective, observational study was conducted involving 60 patients who had undergone surgery or chemoradiation for advanced head and neck cancer. Endoscopic score of swallowing function, penetration aspiration scale (PAS) score measured by videofluorography, and functional oral intake scale (FOIS) score were recorded, and their correlations were examined. There was a positive correlation between endoscopic and PAS scores. Patients with endoscopic scores of 4 points or more had significantly higher PAS scores and lower FOIS scores than those with scores of 3 points or less. These positive correlations were found only in patients who underwent surgery, and not those who received chemoradiation. This study showed the effectiveness of the simple endoscopic method for scoring swallowing function in patients after surgery for advanced head and neck cancers.
